a structural formula

Explanation:

A structural formula simply shows the arrangement of atoms on a compound or molecule.

They are mostly used in representing hydrocarbons.

Through a structural formula we can give name to a compound.

For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.

The bond relationship connecting the species are also shown in this designation.
